Abstract

A card reader device for reading a card having data stored on a magnetic stripe incorporated into the card is disclosed in which the card reader device comprises a read head for passing a magnetic stripe of a card by to read data stored on a magnetic stripe and for producing a signal indicative of data stored on a magnetic stripe, a signal setting device for setting an amplitude of the signal indicative of data stored on a magnetic stripe, and an output jack adapted to be inserted into a microphone input associated with a cell phone for providing the signal indicative of data stored on a magnetic stripe to a cell phone. Data stored on the card and sensed by the card reader device is decoded by components such as a microphone amplifier, an analog to digital converter, and a microprocessor already resident in a cell phone.

Claims

1. A card reader device for reading a card having data stored on a magnetic stripe incorporated into the card the device comprising:

a read head for passing a magnetic stripe of a card by to read data stored on a magnetic stripe and for producing a signal indicative of data stored on a magnetic stripe;

a signal setting device for setting an amplitude of the signal indicative of data stored on a magnetic stripe; and

an output jack adapted to be inserted into a microphone input associated with a cell phone for providing the signal indicative of data stored on a magnetic stripe to a cell phone.

2. The card reader device of claim 1 wherein the read head is inductive.

3. The card reader device of claim 1 wherein the signal setting device comprises a resistor.

4. The card reader device of claim 1 wherein the output jack comprises a 3.5 mm jack.

5. The card reader device of claim 1 wherein the signal indicative of data stored on a magnetic stripe is an analog signal.

6. The card reader device of claim 1 wherein the read head and the signal setting device are contained within a housing.

7. The card reader device of claim 6 wherein the output jack extends out of the housing.

8. The card reader device of claim 6 wherein the housing comprises a slot into which a card having a magnetic stripe may be inserted and swiped.

9. The card reader device of claim 8 wherein the slot has a length and a card has a length and the length of the slot is less than the length of the card.

10. The card reader device of claim 1 wherein the output jack comprises a 2.5 mm jack.

11. A card reader device for reading a card having data stored on a magnetic stripe incorporated into the card the device comprising:

a read head for passing a magnetic stripe of a card by to read data stored on a magnetic stripe and for producing a signal indicative of data stored on a magnetic stripe;

an amplifier for amplifying the signal indicative of data stored on a magnetic stripe; and

an output jack adapted to be inserted into an input associated with a cell phone for providing the signal indicative of data stored on a magnetic stripe to a cell phone.

12. The card reader device of claim 11 wherein the read head is inductive.

13. The card reader device of claim 11 wherein the read head and the amplifier are contained within a housing.

14. The card reader device of claim 13 wherein the housing comprises a slot into which a card having a magnetic stripe may be inserted and swiped.

15. The card reader device of claim 13 wherein the output jack extends out of the housing.

16. The card reader device of claim 11 wherein the amplifier is capable of amplifying a second signal indicative of data stored on a magnetic stripe.

17. The card reader device of claim 16 wherein the output jack is adapted to provide the second signal indicative of data stored on a magnetic stripe to a cell phone.

18. The card reader device of claim 11 wherein the input associated with a cell phone is the line in audio input.

20. The method of claim 18 further comprising the step of providing a housing for containing the read head and the signal setting device.

19. A method for reading a card having data stored on a magnetic stripe incorporated into the card, the method comprising the steps of:
